Which statement correctly compares AB and FD?
AB and FD are the same length.
AB is longer than FD.
O
AB is shorter than FD
AB is shorter than or the same length as FD.
Answers
Answer:
AB is longer than FD.
Step-by-step explanation:
This is an SAS triangle problem.
According to the law of cosines,
c^2 = a^2 + b^2 - 2abcosC
In triangle ABC, a = BC, b = AC, and c = AB
In triangle FDE, a = DE, b = FE, and c = FD.
The only difference is that C is 72° in one triangle and 65° in the other.
We know that cos0° = 1 and cos 90° = 0, so cos72° < cos65°.
In triangle ABC, cosC is smaller, so you are subtracting a smaller number from a^2 + b^2.
c^2 is larger, so c is larger.
AB is longer than FD.
That makes sense because, as you widen the angle between your outstretched arms, the distance between your hands increases.
The statement which correctly compares AB and FD is AB is longer than FD.
What is Triangle?A triangle is a two dimensional figure which consist of three vertices, three edges and three angles.
Sum of the interior angles of a triangle is 180 degrees.
Given two triangles, ABC and DEF.
We have to find the relationship between the sides AB and FD.
Given that,
Sides AC and FE are congruent.
Sides BC and DE are congruent.
Included angles, ∠C = 72° and ∠E = 65°
The side opposite to larger angle will be larger.
So AB is longer than FD.
Hence AB is longer than FD.

A triangular portion of a baseball field is marked as shown below. To the
nearest tenth, what is the length of the side labeled c?
Answers
Answer:
im say your answer is between 1 choice and last choice but I'm say last choice 2.2
Answer:
B. 1.6 yards
Step-by-step explanation:
For the given triangle ABC,
We have ∠BAC = 36° and ∠BCA = 28° and side BC = 2 yards
We have to find length of side labeled as c, so using the sine rule we can say
[tex]\frac{c}{sin28} = \frac{2}{sin36} \\\frac{c}{0.4694} = \frac{2}{0.5877}\\c = 3.4030*0.4694\\c = 1.59\\[/tex]
c is equal to 1.59 which is nearly equal to 1.6 yards so the correct option would be D.
Sathish is going on a 2100-kilometer road trip with 2 friends, whom he will pick up 150 kilometers after he begins the trip and drop off when there are 150 kilometer remaining. The car consumes 6 liters of gas for every 100 kilometers, and gas costs $1.20 per liter.
Sathish will pay for all of the gas when he is alone in the car, but he and his friends will split the cost evenly when they are together.
How much will Sathish pay for gas?
Answers
Answer:
Satish will pay $64.8
Step-by-step explanation:
Kilometres when Satish is alone
150 kilometres in the beginning
150 kilometres in the end
Total: 300 kilometres
Kilometres when Satish is with friends
Total km: 2100
Satish Travelled alone: 300
Kilometres when Satish is with friends: 2100-300 = 1800 km
Litres of gas when Satish is alone
6 litres of gas per 100 kilometres
6 x 3 for 300 kilometres = 18 litres
Litres of gas when Satish is with friends
6 litres of gas per 100 kilometres
6 x 18 for 1800 kilometres = 108 litres
Cost of gas when Satish is alone
$1.2 per litre
18 x 1.2 = $21.6
Cost of gas when Satish is with friends
$1.2 per litre
108 x 1.2 = $129.6
Cost for each friend = $129.6/3 = $43.2
Satish will pay: Cost when travelled with friends + Cost when travelled alone
=$43.2+ $21.6
=$64.8
So, Satish will pay $64.8
Answer:
He will pay $ 64.8
Step-by-step explanation:
Given,
The total distance of the trip = 2100 km,
∵ Sathish pick up his 2 friends 150 kilometers after he begins the trip and drop off when there are 150 kilometer remaining.
So, the number of kilometres for which he and his friends pay the costs = 2100 - (150+150)
= 2100 - 300
= 1800 km,
Now, the quantity of gas for 100 km = 6 liters,
So, the quantity of gas for 1800 km = 18 × 6 = 108 liters,
If the cost of gas is $ 1.20 per liters,
Then the total cost paid by them ( when satish is not alone )
[tex]=\text{gas consumed in liters}\times \text{cost per liters}[/tex]
[tex]=108\times 1.2[/tex]
[tex]=\$ 129.6[/tex]
∵ they split this cost evenly,
So, the share of satish ( when he is with his friend ) = [tex]\frac{129.6}{3}[/tex] = $ 43.2
For the remaining 300 km, he paid the cost of gas,
Again, the quantity of gas for 100 km = 6 liters
⇒ The quantity of gas for 300 km = 18 liters,
Thus, the cost he paid when he was alone = 18 × cost of gas for 1 liter
= 18 × 1.2
= $ 21.6
Hence, the total amount paid by satish = $ 43.2 + $ 21.6 = $ 64.8

The zeros of the quadratic polynomial are
[tex]x=\frac{15\sqrt{5}}{10}[/tex] and [tex]x=-\frac{3\sqrt{5}}{10}[/tex]
The relationship between its zeroes and coefficients in the procedure
Step-by-step explanation:
step 1
Find the zeros
we know that
The formula to solve a quadratic equation of the form [tex]ax^{2} +bx+c=0[/tex] is equal to
[tex]x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}[/tex]
in this problem we have
[tex]4\sqrt{5}x^{2}-24x-9\sqrt{5}=0[/tex]
so
[tex]a=4\sqrt{5}\\b=-24\\c=-9\sqrt{5}[/tex]
substitute in the formula
[tex]x=\frac{-(-24)(+/-)\sqrt{-24^{2}-4(4\sqrt{5})(-9\sqrt{5})}} {2(4\sqrt{5})}[/tex]
[tex]x=\frac{24(+/-)\sqrt{-24^{2}-4(4\sqrt{5})(-9\sqrt{5})}} {8\sqrt{5}}[/tex]
[tex]x=\frac{24(+/-)\sqrt{1,296}} {8\sqrt{5}}[/tex]
[tex]x=\frac{24(+/-)36} {8\sqrt{5}}[/tex]
[tex]x=\frac{24(+)36} {8\sqrt{5}}=\frac{15\sqrt{5}}{10}[/tex]
[tex]x=\frac{24(-)36} {8\sqrt{5}}=-\frac{3\sqrt{5}}{10}[/tex]
step 2
Find the sum of the zeros and the product of the zeros
Sum of the zeros
[tex](\frac{15\sqrt{5}}{10})+(-\frac{3\sqrt{5}}{10})=\frac{12\sqrt{5}}{10}=\frac{6\sqrt{5}}{5}[/tex]
Product of the zeros
[tex](\frac{15\sqrt{5}}{10})*(-\frac{3\sqrt{5}}{10})=-\frac{9}{4}[/tex]
step 3
Verify that
Sum of the zeros= -Coefficient x/Coefficient x²
Coefficient x=-24
Coefficient x²=4√5
substitute
[tex]\frac{6\sqrt{5}}{5}=-(-24)/4\sqrt{5}\\ \\\frac{6\sqrt{5}}{5}=\frac{6\sqrt{5}}{5}[/tex]
therefore
the relationship is verified
step 4
Verify that
Product of the zeros= Constant term/Coefficient x²
Constant term=-9√5
Coefficient x²=4√5
substitute
[tex]-\frac{9}{4}=(-9\sqrt{5})/4\sqrt{5}\\ \\-\frac{9}{4}=-\frac{9}{4}[/tex]
therefore
the relationship is verified

What is the sum of the lengths of the two trails?
Answers
The correct option is B.
The sum of the lengths of the diagonals in the given parallelogram is 12 miles. This value was derived by first identifying the values of the segments in relation to 'y', calculating for 'y', then using the property of the parallelogram where the diagonals bisect each other.
Explanation:To solve for this geometry problem involving a parallelogram, we need to equate the given values and solve for 'y'. The values given stipulate that DE = EB; therefore, we get:
y+2 = 3y-4
y-3y = -4-2
-2y = -6
y = 3
Solving for y, we obtain y = 3.
Next is to solve AE, which is given as CE = AE and substituting the calculated value of y, we get:
AE = 2y - 3 = 2(3) - 3 = 3 miles.
In this parallelogram, it is a property that the diagonals bisect each other. Hence, DE = EB, and AE = EC. Therefore, AC equals 2 * AE = 2 * 3 miles = 6 miles.
Similarly, DB equals 2 * DE = 2 * 3 miles = 6 miles.
Thus, the sum of the lengths of the two trails, AC and BD, is 6 miles + 6 miles = 12 miles.

Answer:
The area of the rectangle is 6x^2(squared)-10x
Step-by-step explanation:
To find the area of rectangles, you must multiply the length by the width. The formst for this is A=LxW. When you substitute each part of the equation in, it becomes 2x(3x-5). When you have parentheses, distribute the number on the outside to each number(or variable) on the inside. First, multiply 2x by 3x. This leaves you with 6x^2(squared). Then, multiply the 2x by the -5. This leaves you with -10x. Combine each part to get 6x^2(squared)-10x. :)

Answer:
x+6y=150
Step-by-step explanation:
If you add 6y to both sides of the equation, it becomes this, making it equal.
Answer:
x+6y = 150 (B)
Step-by-step explanation:
Given the equation x = 150-6y
The equation is also equivalent to
x+6y = 150.
This is gotten simply by taking -6y to the other side of the equation but note that if a function or constant is crossing an 'equal to' sign in an equation, it changes the sign. Considering this equation, -6y changed to +6y upon crossing the equal to sign to give is x+6y = 150 which is the required answer.

344/9 = 38.2 so you would need 39 tables
